"The area is about 18 inches wide. He was in a vertical position. The problem was he was inaccessible to the first responders, to the technical rescue team. So because of that, he was approximately 60 feet up in the air but also below the bridge deck, so we were concerned of fumes," said Todd Plunkett, assistant chief of the technical rescue team for the South Hills Area Council of Governments.

Since the beam was structural, crews had to use a hauling system to free the boy. By entering one of the holes in the beam, they were able to put a harness around him and lower him to the ground.

"A firefighter from Jefferson Hills was able to get himself into the hole with the child ... placed a harness around him and then we used a haul system to actually lift him up out of the hole and onto another system that was attached to a ladder truck that brought him down to the ground," said Plunkett.

After a rescue operation that took two and a half hours, the boy was reunited with his father, who was happy his son was safe but said he's definitely grounded.

"Well, I want to thank everyone, because all the men and women did a great job saving my son from where he shouldn’t have been and he’s not going to be down here fishing anytime soon," said the boy's father, Kirk Sciarretti.

The boy had minor scrapes, but he was going to be OK.

"He’s going to be fine. He’s just a little shook up. I think he was more scared than anything else, said Sciarretti.

Sky 4 helicopter video showed several people working on the ground with a ladder trying to reach the boy during the rescue. Twenty agencies responded to the bridge.

"(The boy) was talking with rescuers the whole time. They were cracking jokes as they were coming down. He was doing very good. He helped them at one point get the harness on him. He did a lot of self-help, which is what we try to do," said Plunkett.

The bridge was closed in both directions while the rescue effort was underway.

"The vehicles driving over the bridge were actually shaking the bridge at one point," said Plunkett. "That’s why the roadways had to be closed down for the safety of personnel, as well as (the boy)."
